As we stated previously, the modern warship has
several radars. Each radar is designed to fulfill a
particular need, but may be capable of performing
other functions. For example, most height-finding
radars can be used as secondary air search radars; in
emergencies, fire control radars have served as
surface search radars.
In this chapter we looked at general radar operation
and the three types of radars most frequently maintained
by ETs. Tracking radars, missile-guidance radars, and
airborne radars are also critical to Navy readiness;
however, they are not normally maintained by ETs and
will not be covered in this TRAMAN.
Because there are so many different models of radar
equipment, the radars and accessories we describe in
this volume are limited to those common to a large
number of ships or shore stations. In our discussion of
specific equipments in the next chapter, we will
purposely leave out older equipment currently installed
in the fleet, but scheduled for replacement.
